JOSEPH J. SMITH, OF NEW YORK, N. Y.

HUMIDIFYING APPARATUS.

Specification of Letters Patent.

Patented N ov. 13. 1906.

Application filed W 8, 1903. Serial No. 156.828.

To all whom, it may concern.-

Be it known that I, JosEPn J. SMITH, a c'tizen of the United States, residing at New ork city, county and State of New York, have invented certain new and useful Improvements in Humidifying Apparatus, of

which the following specification and accompanying drawing represent as an illustration that form of my invention which I now con [0 sider the best out of the various forms in which the principles of the invention may be embodied.

My novel arrangement of apparatus for humidifying the atmosphere of apartments, particularly those in which people are living,

-.1nvolves two associated devicesto wit, a

humidifier with both its intake and outgo passages communicating with the compart ment to be treated and an exhaust device for regulating the degree to which the passage of the air through the humidifier will be repeated. The exhaust is of smaller capacity than the humidifier and may be adjusted to .any degree of capacity within its working By properly setting the relative capacities of the two devices for any given conditions they may be left to run indefinitely without attention, whereas without the regulating action of the exhaust the humidifier if of sufficient capacity to reach and draw throu h it the entire volume of air in the room, as distinguished from creatin a local eddy therein, will soon oversaturate t e atmosphere and render it uncomfortable.

Referring to the accompanying drawing, A re resents a room or apartment of any desire size suitable for the capacity of the a paratus used.

B represents the humidifier, which is of 0 the form shown in other pending applications for patent. It is sufficient to say that it comprises an upright casing C, within which are stretched a series of vertical absorbent sheets D, that are maintained wet by suitable moistening devices, which it is not necessary to describe.

E is a blower driven by an electric motor and servin to pass the air longitudinally alon the s sets from top to bottom. The

inta e of air is through suitable openings F in the upper part of the casing of the humidifier, and the outflow is through similar openingis G in the lower art of the casing.

I is an exhaustlower serving to continually remove from the apartment a portion of the humidified air, being preferably laced in the upper art of the room. The blower H is arranged smaller ca acity than theblower of the humidifier wliich serves to circulate the air of the room through the machine.

Assumin the humidifier B to be started into operation alone, it would soon oversaturate the atmosphere beyond the degree desired; but by simultaneously setting into action the exhaust H the oversaturation is revented, although the entire volume of air in the room may be repeatedly brought into and passed through the humidifier. The action of the exhaust in removing a portion of the air which is replaced by an equal portion of dry air entering through any suitable openin causes the air entering tee humidifier to e less moist by reason of the dry air mingled therewith. than would otherwise be the case. In this manner the entire atmospheric contents of the room may be kept in movement through the humidifier and all of it thoroughly moistened without becoming oversaturated. The processmay also go on automatically and without attention as long as may be desired.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination in an apparatus for humidifying a room or apartment, of a humidifier communicatin with the apartment at both its inlet and out et and having means for passing air repeatedl from the apartment through the humidlfier and back into the apartment, and means for expelling air from the apartment in less quantities than the flow of air through the humidifier, thereby regulating the eflect of the humidifier; substantially as described.

2. The combination in an apparatus for humidifying a room or apartment, of a humidifier communicatin with the apartment at both its inlet and. out et and having means for passing air repeatedl from the apartment through the humidlfier and back into the apartment, and means for expelling air by its size or speedto have a.

from the apartment in less quantities than In witness whereof I have hereunto set my the flow of air through the humidifier, there hand, before two subscribing witnesses, this by regulating the effect of the humidifier, 21st day of April, 1903.

said means consisting of an air-ejecting fan JOS. J. SMITH communicatin at its inlet end with the Witnesses apartment an discharging outside of the G.'W. HOPKINS, epartment; substantially as described. L. S. SHAW.
